Massive PLA blob covering extruder

Hi all,

First off, I'm very concerned that I might have ruined my extruder. I left my printer going overnight and came back to the PLA engulfing the extruder head and wires. I have no idea how to go about removing this mess and would deeply grateful for any suggestions! IMG_2183.JPGIMG_2179.JPGIMG_2181.JPG

First thing id try is to turn up nozzle temp to 260º and carefully try to pull the blob appart.... Often, the worst that can happen is that you break the tiny thermistor wires, but the rest should be fine...
